Today split the page out, it's so damn cool, hahaha

In fact, very common function, today to separate the page, put into an FTL inside, after the words only need to introduce can, really TMD cool a

This article is just a record, I have a cool, not as an example (the code is not fully adhered to), and needs to be improved ...

Front desk use:

< #include "INCLUDE/PAGE.FTL"/>

Background action needs to be set Pagemodel.

public class Pagemodel {private Long Count;   Private long totalpage;   Private long currentpage;   Private long pageSize;   Private map<string, string> pageparams;   Private String Requesturl; Construct method, set, get hidden}

Pagemodel = new Pagemodel (Products.getcount (), Products.gettotalpage (), Products.getcurrentpage (), Products.getpagesize ());p ageparams.put ("key", KeyWord);p ageparams.put ("BP", Bestprice? "True": "false");p Ageparams.put ("LP", LP);p ageparams.put ("HP", HP);p ageparams.put ("CID", categoryId); Pageparams.put ("Prov", ProviderID);p ageparams.put ("order", order);p Agemodel.setpageparams (pageparams); Pagemodel.setrequesturl ("/list");

Of course, PAGE.FTL:

< #if  pagemodel.totalpage gt 1><div class= "Page-nav" >   < #if  pagemodel.currentpage gt 1>        <a href= "${pagemodel.requesturl}?pagenumber=< #if  pagemodel.currentpage-1 gt 0>${ pagemodel.currentpage-1}< #else >1</#if >&pageSize=${pageModel.pageSize}< #list   Pagemodel.pageparams?keys as key>&${key}=${pagemodel.pageparams.get (key)}</#list > "            class= "Ib pre" >&lt;&lt;  previous</a>   </#if >   < #if  pagemodel.currentpage  == 1>        <span class= "cur" >1</span>    < #else >        <a href= "${ Pagemodel.requesturl}?pagenumber=1&pagesize=${pagemodel.pagesize}< #list  pagemodel.pageparams?keys as key>&${key}=${pagemodel.pageparams.get (Key)} </#list > "           class=" IB >1</a>    </#if >   < #if  pageModel.currentPage gt 4>         <span class= "Dot" >...</span>   </ #if >   < #list  0..4 as index >       < #if  index == 2 && pageModel.currentPage gt 1 &&  pageModel.currentPage lt pageModel.totalPage>             <span class= "cur" >${pageModel.currentPage}</span>       < #else >         < #if   ( Pagemodel.currentpage-2+index gt 1)  &&  (pagemodel.currentpage-2+index lt pagemodel.totalpage)  >                 <a  Href= "${pagemodel.requesturl}?pagenumber=${pagemodel.currentpage-2+index}&pagesize=${pagemodel.pagesize} < #list  pagemodel.pageparams?keys as key>&${key}=${pagemodel.pageparams.get (key)}</ #list > "                    class= "IB" >${pageModel.currentPage-2+index}</a>          </#if >      </#if >   </#list >    < #if  pageModel.totalPage - pageModel.currentPage gte 4>         <span class= "Dot" >...</span>   </ #if >   < #if  pageModel.currentPage == pageModel.totalPage>         <span class= "cur" >${pagemodel.currentpage}</span>   <# Else>        <a href= "${pagemodel.requesturl}?pagenumber=${ pagemodel.totalpage}&pagesize=${pagemodel.pagesize}< #list  pageModel.pageParams?keys as  Key>&${key}=${pagemodel.pageparams.get (key)}</#list >             class= "IB" >${pagemodel.totalpage}</a>   </#if >    < #if  pageModel.currentPage != pageModel.totalPage>         <a href= "${pagemodel.requesturl}?pagenumber=< #if  pagemodel.currentpage +1 gt pagemodel.totalpage>${pagemodel.totalpage}< #else >${pagemodel.currentpage+1}</#if >&pagesize=${pagemodel.pagesize}< #list  pagemodel.pageparams?keys as key>&${key}=${pagemodel.pageparams.get ( Key)}</#list > "           class=" Ib next "> next &gt;&gt;</a>   </#if ></div></#if >

You just need to maintain this one page.

Today split the page out, it's so damn cool, hahaha
